The application of NFC security is mainly to virtualize mobile phones into access cards, electronic tickets and so on. The NFC virtual access card is to write the existing access card data into the NFC of the mobile phone, so that the access control function can be realized by using the mobile phone without using a smart card, which is not only very convenient for access control configuration, monitoring and modification, but also can realize remote modification and configuration.
Such as temporary distribution of voucher cards when necessary. The application of NFC virtual electronic ticket is that after the user purchases the ticket, the ticketing system sends the ticket information to the mobile phone. The mobile phone with NFC function can virtually turn the ticket information into an electronic ticket, which can be swiped directly when checking in.
Extended data
NFC and Bluetooth are both short-range communication technologies. Compared with Bluetooth, NFC has long been integrated into mobile phones and gained popularity. NFC has only been integrated into mobile phones in recent years, and so far it has only been integrated into a few mobile phones.
First, the establishment time is different, the NFC communication establishment procedure is simple, and the communication establishment time is very short, only about 0. 1s; However, the establishment process of Bluetooth communication is relatively complicated, and the communication establishment time is long, which takes about 6 seconds.
Second, the transmission distance is different. The transmission distance of NFC is only 10cm, while the transmission distance of Bluetooth can reach 10 m ... but NFC is slightly better than Bluetooth in transmission power consumption and security.
Third, the transmission speed and working frequency are different. The working frequency of NFC is 13.56MHz, and the maximum transmission speed is 424 Kbit/s, while the working frequency of Bluetooth is 2.4GHz, and the transmission speed can reach 2.1mbit/s. ..
